The Analog Devices Inc./Maxim Integrated DS1501YZN-T-R is a Real Time Clock (RTC) IC featuring a parallel interface. This clock/calendar component offers 256 bytes of NVSRAM for data retention, ideal for applications requiring persistent timekeeping. Key features include alarm functionality, leap year compensation, and a watchdog timer for system reliability. The device supports both YY-MM-DD-dd date and HH:MM:SS (24 hr) time formats. Operating within a voltage range of 4.5V to 5.5V for the main supply and 2.5V to 3.7V for battery backup, it maintains accurate timekeeping with a maximum current draw of 5mA at 5V. The DS1501YZN-T-R is supplied in a 28-SOIC package with a 7.50mm width, suitable for surface mounting. It is commonly utilized in industrial control, data logging, and embedded systems where precise time synchronization is critical. The component is delivered on tape and reel for automated assembly.
